PUMPING APPARATUS.

srncrrrcnrron forming part of Letters Patent no. 517,229, dated March e7, 1894.

' Application filed August 21, 1893. SerialNo. 483,660. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM BIRT NEVILL, a citizen of the United States, residing at Rockwell, in the county of Roekwall and State of Texas, have invented a new and useful Pumping Apparatus, of which the following 1s a specification.

This invention relates to pumping apparatus; and it has for its object to provide certain improvements in that class of pumps known as ejectors for raising liquids out of wells by means of compressed air or steam.

To this end the main and primary object of theinvention is to provide certain improvements in apparatus of this character whereby large quantities of water can be easily and quickly raised, and at the same time forced to the point of use by one and the same operation. I

The improvements are particularly intended to supplement those set forth in my allowed application, filed May 19, 1893, Serial No. 474,819.

With these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawingsz-Figure 1 is a perspective view of a pumping apparatus constructed in accordance with this invention. Figs. 2 and 2 are enlarged vertical sectional views of the ejector cylinder and the separator cylinder respectively. Fig. 3 is a central vertical longitudinal sectional view of the aligned air pump cylinders. Fig. 4 is a similar View of the force pump at one side of the air cylinders.

Referring to the accompanying drawings, A represents the combined water and air or ejector cylinder which is adapted to be arranged sufficiently deep within the well so as to have the inlet pipes thereof disposed in the water of the well to provide means for drawing the water from the well and lifting it out of the same to the point of use. The said ejector cylinder A, is closed at both ends and has connected to the upper end thereof the discharge pipe B, provided with a check valve 19, to prevent the return flow of water into the cylinder when once lifted therefrom, and said discharge pipe B, is connected with the force pump devices to be presently described. At a suitable point intermediate of its ends the said ejector cylinder A, has connected to and opening therein at its opposite sides the opposite water inlet pipes O. The water inlet pipes 0, stand 03 from the sides of the cylinder and are provided with the right angularly disposed upper valved ends D, which are either disposedin the water of the well, or have other connections therewith leading into the well, and in either event the same provide means for a free inlet, of a sufficient capacity, into the cylinder, while at the same time preventing the back flow of water out of the cylinder into the well. Normally, the water will not be drawn through the inlet valves into the cylinder A, but during the operation of pumping the water is drawn into the cylinder through the pipes O, by means of the air inlet or ejector pipe E. The air inlet or ejector pipe E, is connected at one end to the lower closed end of the cylinder A, and is provided with an ejector nozzle end F, which projects upwardly within the cylinder A, to a point in a line with or above the connection of the inlet pipes G, with the cylinder, so that as air is passed through the pipe E, under pressure and into the cylinder A, the water will be drawn into the cylinder and ejected out of the same through the pipe B. Y

The pipe E, is provided at a point just below the cylinder A, with a check valve F, whereby water is prevented from rising in the air conducting pipe G. The air conducting pipe G, is connected at one end to the pipe E, and rises from its connection therewith above the top of the well, so that such pipe may be led to any suitable point where it may be convenient to locate the air pumping devices which I shall now proceed to describe.

At a suitable point on the ground and away from the ejector devices just described, is arranged a supporting frame or base H, provided with a parallel series'of transverse supporting brackets I, having semi-circular rest notches J, formed in their upper edges and adapted to receive the horizontal aligned air cylinders K. The horizontal aligned air cylinders K, are arranged in direct line with each other and are provided with inner open ends L adjacently disposed to leave a space there-between, and both of said cylinders are held firmly in the notches of the-brackets by means of the clamp strips M, embracing the top thereof and secured at their ends to said brackets. To the closed ends of the aligned air cylinders K, are connected the valved discharge pipes N, and N, respectively, which pipes are connected at their other ends to one of the coupling necks of a T-coupling 0, secured on one end of the conducting pipe G, so that the discharge from each of said cylinders is led directly through the conducting pipe G, into the ejector pipe already referred to, and both of the pipes N and N, are provided with the check valves n,while the pipe N, which is connected with the cylinder farthest from the ejector devices, is disposed below both cylinders so as to provide convenient connection with the coupling 0.

The aligned cylinders K, which are open at their inner adjacent ends accommodate therein the reciprocating valved plungers P. Each plunger P, comprises the cylindrical plunger body 19, having an exteriorly threaded neck 19, at one end, and an interiorly threaded shouldered portion 19 at its other end. The interiorly threaded shouldered portion 19 accommodates therein the valve Q, and the exteriorly threaded clamp ring q, engagingthe threads of said shouldered portion and work ing-onto the valve to hold the same in place. The exteriorly threaded neck of the plunger body receives the washer packing ring R, held in position thereon by means of the interiorly threaded cap portion 0", engaging the neck 19', and to the cap portion of the plungers in the aligned cylinders is connected one end of the single plunger rod S.

The single plunger rod S, which'connects the plungers in the two cylinders, has attached at an intermediate portion thereof between the inner adjacent ends of said cylinders the sliding cross head T, moving in the parallel guide strips t, arranged at both sides of the adjacent ends of said cylinders and mounted on the supporting brackets of the frame. The said cross head T, is extended at one side as at 15 to receive the connecting rod or pitman t, which is adapted to be connected with any suitable machinery or power for reciprocating the plungers, and the end 25 is also connected with the outer end of the plunger rod U,the inner end of which carries a solid plunger P, and such plunger P works inside of the horizontal force pump cylinder V.

The horizontal force pump cylinder is suitably clamped in position on two of the supporting brackets I, at one side of one of the air cylinders and has connected to the closed end thereof the discharge pipe '0, coupled into one end of a T-coupling o, from the intermediate coupling neck of which leads the valved service pipe 11 which forces the water into a boiler reservoir or any other point of use. The horizontal force pump cylinder is supplied with water from the ejector devices through the water feed pipe W, connected to one end of the T-coupling v, and provided at a suitable point with a check valve to, opening toward the T-coupling so that the pipe W, will be closed when the force pump cylinder is forcing water out through the service pipe 0 The said water feed pipe W, is connected at one end to the bottom of a suitably elevated closed separator cylinder X. The closed separator cylinder X, has connected to the upper end thereof the extreme upper end of the discharge pipe B, from the ejector cylinder, so as to receive the water and air from said ejector cylinder, and said separator cylinder has also connected to its upper end the upper end of the depending air vent or escape pipe Y, which allows the compressed air to find escape from the water separated therefrom in the cylinder X, while such Water passes through the water feed pipe W, into the force pump cylinder as will be clearly understood.

Now from the foregoing it is thought that the operation of the herein described pumping apparatus will be readily apparent. By reason of the air pump devices the compressed air is forced into the ejector cylinder, thereby drawing in water and lifting the same into the separator cylinder X, from which the water separated from the air is drawn into the force pump and discharged to the point of use.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-
